Title: Method for forming optical circuit device
Inventor: KIYONO MINORU
IPC: G02B6/122
Filed: 1988-10-19
Abstract: PURPOSE:To form a small-sized optical circuit device with a satisfactory characteristic at a low price by fixing a plate-shaped optical circuit element along a groove in a position to isolate the optical axis of an optical wave guide in the groove which cuts the optical wave guide with the whole plate block. CONSTITUTION:A plate block 16 to be composed of a same material as a wave guide substrate 13 is adhered and fixed through a buffer layer 16a to one part on an optical wave guide 15. A groove 17 to cut the optical wave guide 15 with the whole plate block 16 is formed in a direction to be orthogonal with the optical wave guide 15 from the upper surface of the plate block 16. A plate- shaped optical circuit element 18 is fixed along the groove 17 in the position to isolate the optical axis of the optical wave guide in the groove 17. In order to cut the optical wave guide 15, which is formed on the surface of the wave guide substrate 13, without sagging or falling, it is desirable to cut it from surroundings in a condition that the optical wave guide 15 is shut in an internal part. Thus, the compact optical circuit device of the satisfactory characteristic not to have the transmission loss of light can be easily formed at the low price.

Title: Picture information reader
Inventor: IKETANI KOHEI
IPC: H04N5/351
Filed: 1992-09-04
Abstract: PURPOSE:To easily correct the irregular light quantity fluctuation of a light source and to read pictures by controlling the charge storage time of a CCD image sensor corresponding to prescribed signals outputted corresponding to the light quantity of the light source. CONSTITUTION:The output of a photosensor 1 is inputted through an amplifier 2 to a VCO 3 and the charge storage time of the image sensor 30 is controlled based on the output frequency of the VCO 3. Pulses synchronized with the output frequency of the VCO 3 are counted by an address counter 38 and when the count of the pluses reaches a prescribed value, a charge transfer pulse is outputted from a driver to the CCD image sensor 30 by a timing pulse outputted from a timing signal generation circuit 34 and the storage of the charge for one line is completed. Thus, when the storage of the charge is controlled, the storage time is shortened when the light source 12 is bright, the storage time is prolonged when it is dark and the fluctuation of the brightness of the light source is corrected for received light quantity in respective periods.

Title: A/d converter
Inventor: SHIOMI TOMONORI
IPC: H03M1/48
Filed: 1992-10-01
Abstract: PURPOSE:To provide a follow-up comparison type A/D converter which causes no fluctuation of the least digital value bit of the A/D conversion result of an inputted analog signal having a fixed voltage level. CONSTITUTION:The adders 8 and 11 and the offset value to the digital value of the A/D conversion result emerging at an output terminal 6. Then these added value are converted into the analog voltage by the D/A converters 9 and 12 respectively. The output voltage of both converters 9 and 12 follow the voltage of the analog signal inputted to an input terminal 1. Therefore an up-down counter 5 stops its counting operation when the voltage of the inputted analog signal is applied between the output voltage of both converters 9 and 12. Thus the digital value of the A/D conversion result never fluctuates.

Title: Burn-in testing board
Inventor: TATO NOBUYOSHI
IPC: G01R31/30
Filed: 1988-10-20
Abstract: PURPOSE:To apply sufficient temperature on ICs under test by providing a cover having excellent heat conductivity so as to cover electronic parts on a circuit board airtightly. CONSTITUTION:Electronic parts to begin with an IC 2 under test which are mounted on a circuit board 1 are covered with a cover 11 which is formed with a material having excellent heat conductivity. At the upper part of the cover 11, a plurality of corrugated parts 11a are formed so that trough parts are located at the upper pats of the ICs 2 under test. Temperature in a constant temperature oven which is not shown is transferred to air in the cover 11 which is not affected with forced blowing through the cover 11. The air at the upper part of the ICs 2 under test is heated by the heating due to the current conduction through the ICs 2 under test, and a natural convection phenomenon occurs. Thus the temperature of the IC 2 under test becomes sufficiently high. In this way, the adequate, continuous operating test at high temperature is conducted.

Title: Light sensing device
Inventor: NOMURA HIROO
IPC: G01S17/93
Filed: 1992-10-02
Abstract: PURPOSE:To simplify an optical system while achieving a transmission light pattern needed for a photosensor by deforming and converting the transmission light pattern using a diffraction grid laid out at the front of a semiconductor laser light source. CONSTITUTION:The light applied from a semiconductor laser 1 is changed into parallel light by a light projection lens 3 and is distributed into three beams, namely a main beam and sub beams with + or -1st diffraction angles through a diffraction grid 2. The projection angle of laser at this time is controlled by adjusting the diffraction angle according to the diffraction grid. At this time, since the light entering the diffraction grid 2 is approximated to a vertical incidence, the diffraction angle can be adjusted easily, an optical system can be simplified since only the + or -1st diffraction angle according to the grid may be considered for the projection angle of laser, thus simplifying and miniaturizing a device and reducing cost. However, since the projection width of 0-order light is almost determined by the aperture of the lens. it is necessary to prepare a large-aperture lens or prevent vertical incidence with the light entering the diffraction grid as diffusion light previously for increasing a projection range.

Title: Magnetism-generating apparatus
Inventor: AKIBA CHIKAKO
IPC: G01N33/543
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To prevent a decrease in measurement sensitivity because of obstructing the reaction between magnetic particle carriers or the reaction between the magnetic particle carrier and an inner wall face of a measurement container, and make measurable in a short time by setting a mechanism which repeatedly generates and stops magnetism. SOLUTION: Two electromagnets 1 and two iron plates 2 are combined and a current of the same direction and the same intensity is made to flow to the two electromagnets 1, thereby, a uniform magnetic field is generated between the two iron plates 2. The magnetism generation time and a magnetism stop time are set by a switch. The amount of the current to be sent to the electromagnets 1 is controlled by a microprocessor. A residual magnetic field is demagnetized by an attenuating alternating magnetic field of 2.5 seconds between the generation and stop of the magnetism. One cycle consists of the magnetism generation time of 30 seconds and the stop time of 30 seconds. After the magnetism acts for 10 minutes, an aggregation image of magnetic particle carriers in a well is observed and judged. From the result, instead of acting the magnetism continuously for 10 minutes, a specimen even if diluted more to a lower concentration can be judged as positive.

The passages 1-7 are provided with 400 pieces of tubes respectively while the passage 8 is provided with 200 tubes, which is half the number in the case of the passages 1-7. The number of equipped tubes is half in only the passage 8 in such a manner whereby the flow speed of water in the passage 8 is increased to double that in the passages 1-7. According to this method, the freezing of the cold water can be prevented and the cold water having a temperature near the freezing point of water can be manufactured.
